Forgive me if you have seen this before, saw it in the comments to a tutorial on finding your own ip address from a script. This was described as being for the visually impaired (and we all know what makes you blind huh?)
mplayer "http://www.moanmyip.com/output/$(curl http://www.moanmyip.com | egrep -m1 -o '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}').mp3" (you can probably substitute any program that plays an mp3 over an http:// connection for mplayer)
